26 Claims. (C1. 40-31)
This invention relates to improvements in ad
vertising devices.
ì
ts object is to provide a simple, inexpensive
mechanism for holding and moving a plurality of
5 flexible sheets independently supported on spring,
rollers in a cabinet and successively unrolling
them across the front of the cabinet.
,
Another object is to provide two continuously
traveling driving mechanisms moving at differ
10 ent but correlated speeds for accomplishing the
desired result.
A still further object is to provide a novel
device for holding the free ends of the sheets
to compensate for irregularities in them andin
15 order to prevent wrinkles in them when they are
unrolled, to insure proper re-rolling and to pre
vent them from being subjected to undue strains.
These and other objects will appear in the fol
lowing speciñcation, in which I will describe an
embodiment of the invention, the novel features
of which will be set forth in claims.

is attached; and
Figs. 13 and 14 are sectional Views of details,
the sections being taken on the lines I3-I3 and
I4-l4, respectively, of Fig. 3.
Like characters of reference designate similar
parts in all figures of the drawings.
I0 designates a cabinet within which all parts
of the device are enclosed.
H3A designates the
side plates which support parts of the mecha- 5
nism within the cabinet.
il is a window in the
front Wall of the cabinet, preferably covered by
a panel of glass or other transparent material.
l2 is a motor and i3 a reduction gearing, the
shaft of which drives a bevel gear i4 and a pulley 10
l5. The gear lli is connected through reduction
gears which include a worm i6 to drive a shaft
I1. Fast on shaft l'l are index plates i8, I8
lnotched at spaced intervals, as shown at I9
15
(Fig. 3).
The pulley I5 is connected by a belt 20 with a
pulley 2l affixed to a shaft 22.
Fast on a shaft 22
are sprocket wheels 23, 23. These drive chains
24, 24 which run under sprocket wheels 25, 25
on shaft I'l, but mounted to rotate thereon. Hooks
23, 26 are pivotally mounted on the chains 24, 24
horizontally opposite each other.
The display sheets 30 are mounted on spring
rollers 3l, the» pintles 32 of which are a?ñxed to’
brackets 33. One of the roller brackets 33 is
shown in detail in Figs. 6 and '7. Each of these
has a hub 34 with a concentric bore into which
the roller pintles ñt.
is slotted, as at 35.
The other end of the hub
Intermediate the ends of the
hub is a transverse body, the lower part of which,
when the bracket is in the position shown in Figs.
6 and '7, forms a lug 36, the end of which is con
veXly curved on an arc concentric with the hub.
The upper part of the body forms a flange, the
upper end of which is concavely curved on the
same radius as that of the end of lug 33 to form
a saddle 31. Transverse lugs 38 project from
one side of the ñange to form between them a
space of the width and in alinement with the slot
35. A notch 39 which is offset from the slot 35
and lugs 38 is formed in one of the upper corners
of the flange.

40 is a cross bar which is shownin detail in
Figs. 8, 9 and 10.
of metal.
It is a substantially flat strip
Parts of each of its ends are bent, as
shown, to form slots lll. Spaced inwardly from
the slots 4l are lugs ¿32 which project beyond the
slots. 43 is a lug projecting from the center of
the other side of thebar. This is apertured to
receive a cotter pin 44 for a purpose which Will 50
appear presently.
45 is a compensator bar Which is shown clearly
in Figs. 11 and 12. This is made of sheet metal
bent along a longitudinal line to form two layers
. 46 and 4l, centrally apertured at 4B.
2
.2,122,153
The free end of a display sheet 30 -is folded over
the upper edge of the layer 41 and extends down
between the layers 41 and 4E. The parts thus
mit this roller engagement to be released. Its
engagement will be continued, however, until the
assembled are placed on a cross bar 40 with its
of it, thus supporting the unit until it is seated
lugs 43 passing through the aperture 48 therein,
puncturing two layers of the display sheet. The
Cotter pin 44 is then put through the lug 43 to
hold the parts together. The compensator bar
on the one ahead of it. At that time its saddle
31 will engage the lug 36 of the bracket ahead of
it. The hook will be forced back against the part
62A of its rail by the retarded movement of the
45 is bowed longitudinally to some extent so that
it has to be pressed against the cross bar tolV clear
roller bracket and will pass down clear of the
column of units. At 62B the position of the 10
the cotter pin hole in lug 43.
>
It will appear that the cross bar 4U is moved
transversely, in a manner to be fully described.
This motion will be transmitted to the display
sheet by a pull exerted in the middle of the com
pensating bar. The latter is capable of rocking
somewhat on the cross bar so as to compensate
for irregularities in the display sheet and to
distribute equally thereon all tensional strains.V
This causes the display sheet to be held in a ñat
condition as it is unrolled and prevents the for
mation of wrinkles therein. This. also insures
long life of the display sheet. Another advan
tage of this central pivotal support for the free
25 edge of the display sheet is that it makes it re
roll properly.
60 and SI are parallel tracks añixed to the side
plates IOA within the cabinet. These are straight
throughout the greater part of their length, but
30 curved at the top and bottom of the cabinet. The
slots 35 and lugs 38 of the roller brackets run on
the track 6B.
The slots 4I of the cross bars- run
on the track 6I. It is understood that similar
guides are on the opposite side plate.
62 is a continuous rail back of the hook 26 sup
f1.3 Ul
ported on a ñange 63 affixed to the side plate I 0A.
The parts of this rail designated by 62A and 62B
are parallel with the chain 24, but spaced there
from a sufficient distance to let the hooks 26 swing
40 clear of the roller brackets 33. At 62C the rail is
curved outwardly to a plane at the rear of the
chain. When the hook reaches this curved por
tion B2C of the rail it is pushed outwardly there
by into the position in which it is shown in full
45 lines in Fig. 3 to engage the hub 34 of a roller
bracket as it leaves the slot I9 in index wheel I8
and to engage the lug 42 of the cross bar of the
next succeeding unit. The rail 62 will maintain
the hook in its engaging position as it moves up
50 wardly across the window I I. This upward
movement raises the roller bracket of one unit
and allows its display sheet which has previously
been unrolled toy re-roll. At the same time it
raises the cross bar 4U of the succeeding unit and
55 thereby unrolls its display sheet 30, as at this
time the roller bracket of this succeeding unit is
held back by its engagement with a slot in the
index wheel.
When the cross bar which has been thus raised
60 reaches the upper end of the movement imparted
to it by the hook 26, a spring 'I0 engages its lower
edge and holds it against the action of its spring
roller with its display sheet distended before the
window Il.
At the same time an offset 62D in
the hook rail permits the hook to drop back to
the position indicated at 26A, far enough to be
come disengaged from the lug 42 but not enough
to» become disengaged from the roller bracket
which it has just raised. At that time the notch
39 of the roller bracket which is in the hook will
engage the cross bar 40 of its own unit.
The part 62E of the râîl is on an arc of suffi
cient radius to maintain the engagement of the
hook with the roller bracket. At S21-ï' the rail is
75 bent inwardly to merge with its part 62A to per-
roller bracket in the hook engages the one ahead
hook as it is beginning to release is indicated. It
is shown `fully released at 26C.
'I'he units will then move down by gravity until
the hubs 34 of their roller brackets are engaged,
one unit at a time, by the index wheel I8 which
’carries them around to the position at which
they are engaged by the hooks 26. The weight of
this column of units is applied to the periphery
of the index wheel. The movement of the column
of units is retarded but not stopped by the index 20
wheel gearing.
The driving mechanism which I have described
is so arranged that the index wheel I8 moves pe
ripherally a distance equal to that between two
of its slots I9 while the hook makes one complete 25
cycle of its movement. Thus, the cross bars 40
are picked up and raised quickly the full height of
window I I while the rollers move upwardly slow
ly a distance equal to the space between the slots
I9. The result is that the display sheets are con 30
secutively distended over the window I I and re
main in that position during more than half of
the movement of the hook.
In order to hold the hook out of bracket en
gagement as it passes around under shaft I‘I, a 35
rail 80 is provided. This is supported on brack
ets 8| aiñxed to the rail portion 62B which is bi
furcated where it passes the sprocket wheel 25,
as shown in Fig. 14. 82 is a spring affixed to rail
80 and arranged to bear on chain 24 to keep it 40
under proper tension.
The rail 62 at the front of the cabinet is
widened to allow the chain 24, as well as the hook
26, to bear upon it between the sprockets 23 and
25. On the other side it is oiïset, as shown at 83
in Fig. 13, between the sprockets 23 and 25 to pro
vide a bearing for the back of the chain on this
side.
The display units are not interconnected. The
number of them placed in the cabinet may there
fore be varied at will and with ease. The dis
play sheets may be paper posters, pieces of textile
material, samples of wall paper, or any other
desired flexible material. The entire area of the
back of the display sheets is `clear of obstruction,
so that they may be illuminated from the rear
if desired.
The mechanism shown and described is a. sim
ple embodiment of my invention. Structural
modiñcations may be made within the spirit and 60
scope of the invention and I intend no limita
tions other than those imposed by the appended
claims.`
